/** See the comment at the top of field_5x52_impl.h for more details.
*
* Here, we represent field elements as 10 uint32_t's in base 2^26, least significant first,
* where limbs can contain >26 bits.
* A magnitude M means:
* - 2*M*(2^22-1) is the max (inclusive) of the most significant limb
* - 2*M*(2^26-1) is the max (inclusive) of the remaining limbs
